| Abstract: Upconversion nanoparticles have been limited to further development in the field of application due to their low luminescence efficiency. Surface plasmon modulation using noble metal has been developed as an effective way to enhance upconversion luminescence. In this work, the noble metal ricelike structure with a simple synthetic procedure was obtained through regulating the localized electric field around upconversion nanoparticles for improving upconversion luminescence intensity. The 3D finite element method was employed to investigate the effect of the different contact modes between Ag rices in the actual films on induced localized electric field enhancement. Further, this enhancement effect caused by plasmon-coupling is a crucial contribution in this upconversionmodulated system. And the upconversion intensity improvement of nearly 100 times was acquired. Finally, the upconversion luminescence performance can be further optimized by adjusting the thickness of the plasmonic layer and luminescence layer. |
